Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description must carry the full behavioral disclosure burden. It only mentions billing, not what the tool does (e.g., returns a discography list), side effects, or safety. It fails to disclose any operational behavior.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is short but poorly structured: it mixes a tautological title, a redundant group label, and billing details in a run-on. Most content (billing) is not relevant for tool selection, and the useful purpose is absent.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple tool with one parameter, no output schema, and no annotations, the description provides almost no context: it doesn't state what the tool returns, how it differs from other artist endpoints, or typical usage. An agent cannot confidently select this tool over siblings.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The single parameter 'id' is fully described in the schema with a clear 'Artist ID' description (100% coverage). The description adds nothing about parameters, so the baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description merely repeats the title ('Artist discography overview') with a typo ('disciscography') and adds 'Group: Artists', which is redundant. No verb or specifics distinguish it from sibling tools like get_v1_1_artist_albums or get_v1_1_artist_overview.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus other artist-focused tools. The only extra info is billing (cost and payment method), which is not about usage context or alternatives.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
